Creality (Ender 3) Filament holder 80mm spools End Block

thingiverse

I've been using mjoaris's excellent spool holder (https://www.thingiverse.com/thing:3209211), but several users' comments about the spools falling off raised concerns, prompting me to create a quick and dirty snap-on blocker for the end. I primarily use it for long and unattended prints. To install, pull upwards to snap it in place. To remove, pull back on one of the clips; be careful not to damage your fingernails. At some point, I plan to add a piece that will make removal easier, but my daughters are currently demanding chickens, puppies, and ducks wearing sorting hats. If you're using a 100kg spool or your printer is leaning back at a 45-degree angle, don't rely on this setup. However, so far it has worked perfectly for me.
